I'm seeing similar on my cache pool devices. After upgrading there were thousands of corruption errors. I have two pools, one for apps cache and one for cache I reset both counters, and the apps cache stopped increasing, however the cache continued to increase slowly. I turned off spindown on both drives and it stopped increasing for a while, however started to slowly climb again over the following 24h. Memtest passes without error. The drive passes short and extended testing without error. Identification: Samsung_SSD_990_PRO_2TB_S7DNNU0Y714679D (nvme1n1) pool device stats: Id Path Write errors Read errors Flush errors Corruption errors Generation errors
